New suggestion

Can a game be set up where a there is a box (say size 20 x 20) similar to battleships and all can click on a box and a different value is under each box (just numbers), the contestant can have say 5 goes a week and the box is changed each week (values moved around and altered)with a prize awarded to the contestant who has the highest aggregate total over four or a suggested number of weeks, how about a booby prize for the contestant with the lowest total having used all their goes to keep the interest for all ?. The hidden values could vary greatly such as from 1 to 1000 so giving even the unlucky ones on the first week or two a good chance of winning.
